water plays a key role in sustaining life on earth. it has unique properties due to its chemical structure. determine whether each statement is true or false. the oxygen atom in water has a slightly positive charge. hydrogen bonds can form between water molecules. a water molecule has a bent shape. in a water molecule, valence electrons are shared between one oxygen atom and two hydrogen atoms.

water plays a key role in sustaining life on earth. it has unique properties due to its chemical structure. determine whether each statement is true or false. the oxygen atom in water has a slightly positive charge. hydrogen bonds can form between water molecules. a water molecule has a bent shape. in a water molecule, valence electrons are shared between one oxygen atom and two hydrogen atoms.

Answer

Brief Explanations:

  1. In a water molecule, oxygen is more electronegative than hydrogen, so the oxygen atom has a slightly negative charge, not positive. So the first statement is false.
  2. Water molecules can form hydrogen - bonds between them due to the polar nature of the water molecule. So the second statement is true.
  3. A water molecule has a bent shape because the oxygen atom has two bonding pairs and two lone pairs of electrons, which repel each other according to VSEPR theory. So the third statement is true.
  4. In a water molecule ($H_2O$), the oxygen atom shares valence electrons with two hydrogen atoms through covalent bonds. So the fourth statement is true.

Answer:

  1. False
  2. True
  3. True
  4. True
